Maintaining QoS for publish/subscribe middleware in dynamic environments
Joe Hoffert, Douglas C. Schmidt · 2009
Emerging trends and challenges. The number and type of distributed systems that utilize publish/subscribe (pub/sub) technologies are growing due to the advantages of performance, cost, and scale compared with single computers [1, 2]. Examples of pub/sub middleware include Web Services Brokered Notification (www.oasis-open.org/committees/tc_home.php?wg_abbrev=wsn), the Java Message Service (JMS) (java.sun.com/products/jms), the CORBA Event Service (www.omg.org/technology/documents/formal/event_service.htm), and the Data Distribution Sendee (DDS) (www.omg.org/spec/DDS). These technologies support data propagation throughout a system using an anonymous subscription model that decouples event suppliers and consumers.
